Nitrogen–Iodine Exchange of Diaryliodonium Salts: Access to Acridine and Carbazole
摘要:
A nitrogen iodine exchange protocol of diaryliodonium salts with sodium azide salt is developed for general construction of significant functional acridines and carbazoles, in which introduction of nitrogen at a late stage was successfully established avoiding heteroatom incompatibility. Inorganic sodium azide served as the sole nitrogen atom source in this transformation. The diversiform functional acridines and carbazoles were comprehensively achieved through annulated diaryliodonium salts, respectively. Notably, Acridine orange (a fluorescent indicator for cell lysosomal dye) and Carprofen (a non steroidal anti-inflammatory drug) were efficiently established through this protocol.

Novel azaheteroaromatic derivatives of 2-styrylanthracene: 2-styrylbenzo[g]quinoline and 3-styryl- acridine were obtained from 3-nitro-2-naphthaldehyde and 2-bromo-4-methylbenzoic acid. Spectralproperties of the new compounds were studied.

Copper-catalyzed tandem cyclization reactions between arylboronic acids and anthranils have been established, providing new approaches for one-pot assembly of azacycle acridines. This one-potprotocol features simple operation, precious-metal-free conditions and good functional group compatibility, thus providing an efficient approach for the synthesis of a variety of acridines in moderate to good
An efficient and convenient palladium-catalyzed reductive system by employing sodium hydride as the hydrogen donor and acetic anhydride as an activator has been developed for transfer hydrogenation and acetylation of a wide range of N-heteroarenes including quinoline, phthalazine, quinoxaline, phenazine, phenanthridine, and indole. Moreover, acridine substrates could be directly reduced without the
